Zimbra Collaboration Reviews

Just using ZCS 8.0.9 as email solution for about 60,000 users, with a big email data of 60 Tb (60,000 users * 1 Tb/user)

Security & performance issues (60,000 user):

- Don't support or guide how to integrate with MFA (Multi-factor Authentication)

- Backup & Recovery for 60 Tb email data is hard (60,000 users * 1 Tb/user); no effective solution for backup & recovery for such a case.

- Don't support DLP (Data Loss Prevention) solution.

- HA (High Availability): just support at the server (VMs) layer, don't support at the service layer.

- It is hard to upgrade ZCS 8.0.9 to ZCS 8.8.15 OSE .

This is a good email solution and it's open-source which is great and the most important feature for us. 

There are security & performance issues which is one of the concerns of using an open-source product.

I've been using this solution for 10 years. 

Technical support for the open-source version is softer than for the commercial version. If we get the commercial version we'd be happier with the technical support. 

an in-house team.

We've been evaluating other options. Microsoft Exchange is very popular in the large enterprise sector. It's more popular than G Suite or Zimbra.

Zimbra has the open source version and also a commercial version. There's a difference in terms of security and other features between the two versions, 

I rate this solution a six out of 10.

We are mostly using Zimbra Collaboration for email purposes. It is also a collaborative tool. We also use it for sharing some documents and for meetings. 

Zimbra Collaboration is light to manage. It works on the Linux operating system, which is far better to manage than Microsoft Windows. Microsoft Exchange works only on the Windows server. We prefer working on the Linux server for security reasons and ease of management.

Zimbra Collaboration also has some integrated tools for security. It some modules to fight malware. These modules are not very powerful but are still doing a great job. Microsoft Exchange doesn't have a basic module. You have to purchase a security solution and add it to the solution. 

The cost of Zimbra Collaboration is one more reason for liking it. It is also very simple to migrate from Zimbra Collaboration to another email solution.

Zimbra must improve its solution to make it easy so that the users don't have to use webmail to connect to their accounts and log in to webmail every time. This is something that is lacking in Zimbra Collaboration. They should provide a better way to easily connect email applications on the desktop to the Zimbra server.

They should also try to have more functionality for storage management, like Microsoft Exchange. Currently, the management of the email data must be done manually in Zimbra Collaboration, which we are finding very difficult. They should provide a way to save emails so that you can have more space on the server and storage. Because of the lack of this functionality, we are planning to migrate to Microsoft Exchange. Microsoft Exchange provides a better way to manage storage than Zimbra Collaboration. You cannot have a mail solution without storage management because emails will always increase. 

Zimbra Collaboration also needs tools for management. More back-office tools are required to manage the whole mailbox and space. You don't only manage emails but also the documents attached to the emails. Therefore, you require tools to select and decide what do you want to save or how do you want to free up space in your infrastructure.

I have been using Zimbra Collaboration for almost six years.

Zimbra doesn't have good technical support. They are not always available for help, so we have to troubleshoot as much possible by ourselves. It is not easy to find help when we have any incidents.

We have a local partner who is an expert in Zimbra. They really help us by trying their best and doing what they can do. Zimbra support is not always available, so we work only with local support.

Because Zimbra doesn't provide good support, it was difficult for our administration team to handle this solution in the beginning. They had to learn it on their own. The initial setup, however, wasn't really difficult. It was simple.

The teams in charge installed it in a short time with the help of a partner.

Zimbra Collaboration is less expensive than Microsoft Exchange. Zimbra works for small companies because it is not expensive. 

Zimbra Collaboration has more security tools than Microsoft Exchange. If you are choosing between Zimbra Collaboration and Microsoft Exchange, you have to take into account the cost of security tools with Microsoft Exchange. When you purchase Microsoft Exchange, you will also have to purchase tools for security, which adds to the cost. 

The migration from Zimbra Collaboration to another email solution is very simple and easy. Migration from Microsoft Exchange to another email solution is very difficult. Microsoft doesn't allow migration that easily. In fact, you have to pay for tools to do that. You have to buy some expensive tools to migrate.

I would recommend this solution, but it depends on the size of the company and the cost. The number of emails that you use impacts the cost of the solution. 

For a small company, Zimbra Collaboration is good because it is simple, inexpensive, and not very difficult to deploy. For a big company, Microsoft Exchange is good because you have to manage the data, storage, and user emails, and you need a tool that can easily do it for you. Microsoft Exchange provides tools to manage the space and the server. You can create your own policy for emails. For example, you can save emails that are two years old somewhere else. Zimbra Collaboration currently does not have such functionality, and it is something very inconvenient because the emails keep on increasing, and the storage is not unlimited. Therefore, you have to find a way to manage the storage to save all emails and have free space for the new ones. This functionality is really powerful in Microsoft Exchange. That's why for a big company with 1,000 or more users, it's good to have Microsoft Exchange. It, however, also depends on your budget.

I would rate Zimbra Collaboration a seven out of ten. In spite of the lower cost of Zimbra Collaboration as compared to Microsoft Exchange, our management is planning to migrate to Microsoft Exchange because of the issue with storage management.

We use the solution for emails.

The configuration is simple.

The product must be more customizable.

I have been using the solution for two years.

The tool is stable. I rate the stability a five out of ten.

There are 10 to 20 users in our organization.

The initial setup was moderately difficult. I rate the ease of setup a five out of ten. The deployment took a few days. We have five domains. It was not easy for all the domains. The guides are very good and easy to read.

We use the free version.

We also use Nextcloud and Seafile.

Overall, I rate the product an eight out of ten.

I use the product for the main server.

Network NG Modules are valuable to us. They are very high modules. The solution has features that can help administrators and users to manage the server. It is the best tool.

The only problem I face with the product is spam. I do not have any other big problems. The antispam and antivirus features are hard to understand on mobile devices. The solution should improve the features to provide more clarity to the users.

I am using the solution currently.

The product is stable. I rate the stability an eight out of ten.

I rate the solution’s scalability a nine out of ten. It is very scalable.

The initial setup is easy for system administrators.

The deployment took one hour.

The solution is not expensive compared to other products. It is cheap.

I know others who use the solution in their organization. I would recommend the tool to others. Overall, I rate the solution an eight out of ten.

Our primary use case is for email purposes.

I would like to see a Microsoft schedule function added. In addition, some additional appearance and convenience features would be nice.

The most valuable feature of Zimbra Collaboration is the cost.

I have been working with Zimbra Collaboration for the past three or four years.

In general, the overall stability is good.

The initial setup was straightforward and not difficult.

Zimbra Collaboration has a better price than Microsoft.

When you compare it to Microsoft the only major difference is the scheduling and advanced scheduling feature

I would rate Zimbra Collaboration and eight out of ten.

We have customers that are using the on-premise version of Zimbra Collaboration and others are using the cloud.

We Zimbra Collaboration to send and receive email primarily. Additionally, we use it for collaboration, sharing documents, and calendar contacts. It's a solution for massaging and collaboration.

The backup and storage management features of Zimbra Collaboration are valuable.

Zimbra Collaboration could improve the migration from a basic solution to a more containerized solution. For example, the installation should be able to extend to the containers and manage them with some solution, such as OpenShift or Kubernetes.

The video conference solution Zimbra Connect is a mediocre solution for video conferences. They should make it more similar to Office 365 and add some collaboration with other solutions, such as Alfresco.

I have been using Zimbra Collaboration for approximately two years.

Zimbra Collaboration must work on the high availability of the platform.

I have found Zimbra not to be very stable. If we see in one node, we have a lot of patches and collective principles of security. Zimbra is not very stable, but it's okay. We can see some bugs in the Zimbra Collaboration but they release patches to fix them. For example, in the last patches, they corrected a vulnerability that could have caused an attack with Log4j.

This solution is scalable horizontally and vertically

Zimbra Collaboration is suitable for all sizes of companies, small, medium, and large companies, such as government, industry, and media.

I have been satisfied with the support.

The initial setup of Zimbra Collaboration is straightforward. However, we must be the administrators of Linux because we need to have access to the command-line to install it. We cannot install it with the graphic interface. We must have the ability to manage some command line code in the systems of Linux.

The time of the deployment depends on the complexity of the architecture. For example, if we install it in one node, it can take a maximum of one hour. However, when we install in the multi-node system. A complex installation can take over three days.

We provide the services for our customers, the fabric, and the training centers.

The price of the solution is low. 

The total cost of our projects is low. For example, if we compare Zimbra Collaboration with Microsoft, the license of one account they are probably the same price. However, after the initial licensing, to add more options or use features in the Microsoft solution you must purchase them. In Zimbra, when we buy a license, there are only two levels of license. If we buy the premium license, we have almost all the features activated in our license.

My advice to those wanting to implement Zimbra Collaboration is they will have to have some experience in the manipulation of Linux systems. If there are issues with Zimbra Collaboration there should be someone with experience. If there is no one with experience with the ability to manage Linux systems, you will not be able to troubleshoot any problem in Zimbra Collaboration.

I rate Zimbra Collaboration an eight out of ten.

Zimbra Collaboration is useful for small to medium organizations, such as educational institutes, schools, and universities. For big businesses and enterprises, I do not this it is as useful. There are some other useful solutions, such as Office 365 and Google Cloud which would be better suited.

The logs, troubleshooting, and tracking we have found to be the most valuable features. We have any issues with lost messages the features are useful. It is very easy to track and log.

I have been using Zimbra Collaboration for approximately 10 years.

Zimbra Collaboration has been stable.

I have found Zimbra Collaboration to be scalable but could improve.

We have approximately 400 to 500 users that use this solution.

We do not have plans to increase usage.

I have been satisfied with the technical support from Zimbra Collaboration.

The installation is not straightforward, it can take two days for the full implementation.

We used help from an integrator for the implementation.

We have approximately four administrators and engineers that support this solution.

We do not pay for licenses to use this solution.

I would recommend this solution for small to medium-scale businesses.

I rate Zimbra Collaboration a seven out of ten.

While I believe that Zimbra nine is the latest update, I am working with eight. 

The solution employs open source software. 

I implement the solution so that our end user customers may have mailing features, one-on-one chat facilities and unified communication. Within one's email are contained his calendaring facilities. 

One of the most valuable features involves the solution's automatic backup, which I find to be pretty simple and straightforward, and obviates the need for additional software. The web client features have good graphics and are pretty useful. 

It would be great if a group chat feature were created to allow for a team environment. The current chatting facility only allows for one-to-one chats. 

I have been using Zimbra Collaboration for nearly two years.

The product is very stable. One need only implement it, at which point it does not require further contemplation. Only basic maintenance is required. 

The solution is easy to scale. It boasts scalability features such as those allowing an additional server to be added for horizontal scaling.We have encountered no issues in this regard. 

We have not required much technical support, as the implementation we do primarily concerns the community edition with which we started. We feel the technical support to be good. They supply good email support. We do not require this at the moment. 

Nearly two years back, I was working with Microsoft Exchange. 

The advantage of Microsoft Exchange over Zimbra Collaboration is that it is very heavy and has much more features, but its management requires a person to have a greater level of skill. Microsoft is also a more mature solution. 

When it comes to the licensing of Zimbra Collaboration, my license covers the servers and I find its terms to be much simpler than those of Microsoft Exchange. Microsoft has multiple requirements, such as one concerning the need for the best OS licenses. There are multiple products needed to get Microsoft Exchange to work, but there is also a standalone option available. The licensing of Zimbra Collaboration is better than that of Microsoft Exchange and it's more affordable. 

The initial setup is simple. As the implementation is pretty simple, a small organization can initially make use of the community edition and move on from there. 

The management of the solution is simple. Save for mailbox related issues, the maintenance of the solution is minimal. Issues are limited to comparatively minor ones and mainly would arise at the SMTP end.

The product is on the client side, so our company provides implementation and support services. 

The solution is best suited for medium enterprises, although my organization supports mainly government organizations which range from medium to large. 

I rate Zimbra Collaboration as an eight out of ten. 

We are using it as an email server and collaboration suite.

It has all collaboration features, such as document sharing, video conferencing, chatting, task sharing, and calendar sharing.

It is awesome in terms of stability and scalability.

Zimbra should provide a desktop client. Right now, we are using a web browser for accessing our emails. There should also be a desktop client.

I have been using this solution for approximately nine years.

Its stability is very good.

Its scalability is very good. We have approximately 900 users. We have one person for its maintenance.

Their technical support is good.

We migrated from IBM Lotus Domino.

We are using perpetual licenses. We have deployed it in our local data center, and we buy perpetual licenses on a per-user basis.

I would rate Zimbra Collaboration an eight out of 10.

Zimbra is open source. They got absorbed by Yahoo, but they're still primarily open-source and have continued to extend their technology. A lot of other products like Microsoft Exchange offer email or collaboration features, but they are not as fast as Zimbra. And with Exchange, it's not easy to purchase the license. And Zimbra is more reliable in terms of integration.

Yahoo acquired Zimbra, and Yahoo Mail is a web-based email, not a software platform. So as part of the acquisition, they have to continue providing support to the open-source license holders. But lately, they have decreased their support for the open-source community, and they're pivoting to the enterprise market. So they're starting to transition to a proprietary cloud-based solution. And when they adopt this proprietary solution, it won't be good. So hopefully, in the future, they'll continue to offer an open-source version. That's what makes Zimbra trustworthy for users as an email host. Email is still essential for communities and businesses. Even if you are currently using instant messaging or any communications tool, you still need email. 

Maybe Zimbra can improve by implementing an architecture that mimics social media, like offering short messages instead of just email. Instant messaging can mean light messaging or group messaging, like a B2B chat or something like that.

We've been using Zimbra for about four or five years.

Zimbra is roughly as scalable as Microsoft, but I haven't deployed Zimbra for any huge clients yet. For example, all of my clients have fewer than 2,000 users. So if they had more than 2,000, I couldn't say whether Zimbra could manage that or not. But I know that Microsoft can work with clients that serve 10,000-plus users. 

So in my experience, I can confidently say that Zimbra is good enough for 2,000 client users. But, at the same time, if my client needs more than that and we have two options—Zimbra or Microsoft—I'm going with Microsoft because many admins will speak to Microsoft's ability to handle that many.

It's easy for me because I have worked with Zimbra concepts since Yahoo acquired it in 2007, but I can't speak for the average users.

I rate Zimbra Collaboration eight out of 10. It stacks up well compared to OWA or Microsoft Exchange. I've developed solutions for my clients using all of these. And compared to other web applications, I prefer the web-hosted Zimbra. I think Zimbra is more reliable and competitive than Microsoft because they offer an open-source version.
